Gratitude is the proof of realizing God's sacrifice and love. It is also appreciation to overflow with joy, happiness, and love in everything. We, the sinners who deserve to die, have been saved and go to eternal heaven, and the pain and suffering in this land is just a brief shower. Overflowing gratitude gives us joy and pleasure, and it is expressed in laughter. As the saying goes, "Train to be godly," in order to go to heaven, which is full of joy and gratitude, we need both train to be joyful. God is leading his children to live a life of faith in joy. We should always be able to think of God the Mother, think of Her teachings, and share joy and happiness with each other. Let us always be happy by God who saved us, and let the sound of sadness and sighs be transformed into a sound of joy and prosperity.
